Is bandwidth same as frequency?

The basic difference between the two is that frequency is defined as the rate of radio signal to send and receive communication signals, whereas bandwidth is defined as the difference between the highest and the lowest frequencies of a signal generated .

The bandwidth can be referred to as the range of the component frequencies that is contained in the signal. It can be said that the bandwidth is directly proportional to the signal . Larger the bandwidth is larger the frequencies it can contain.

The bandwidth of a signal is defined as the difference between the upper and lower frequencies of a signal generated. As seen from the above representation, Bandwidth (B) of the signal is equal to the difference between the higher or upper-frequency (fH) and the lower frequency (fL) .
